RUG AND CARPET CLEANING MACHINE.

Specification of Letters Patent.

Application filed September 7, 1915. Serial No. 49,174.

To all whom it may concern:

Cleveland, in the county of Cuyahoga and following features of noveltyand improvement.

It is so constructed as to permit the cleaning of large and small rugsand to perform the operation thoroughly in a machine not larger thanwould ordinarily be required to clean a small rug.

, The invention includes the combination and arrangement of parts andconstruction of details hereinafter described, shown in the accompanyingdrawings and specifically pointed out in the claims.

In the accompanying drawings Figure 1 is a front elevation of themachine; Flg. 2

is a longitudinal'section thereof on line 2,

Fig. 5; Fig. 2 is a transverse section of the beater shaft and sleevethereon; Fig. 3 is an end elevation of the machine showing the operatingmechanism therefor; Fig. 4 is an elevation of the opposite end of themachine; Fig 5 is a transverse section of the machine on line 5, Fig. 1;Fig. 6 is a perspective of v the apertured grating over which the rug isbeaten. Fig. 7 is a transverse section thereof enlarged; Figs. 8 and 9are sectional views of the clamping and securing means for therespective extremities of the spring guard rods, Figs. 10 and 11 are aplan and transverse section respectively showing the device forreleasing the friction roll, from the friction disk; Fig. 12 is alongitudinal section through the beater shaft; Fig. 13 is an enlargedportion thereof; Fig. 14 is a side elevation'of operatinggears showingthe cam clutch in the engaging position. v

In these views A is a hollow casing in which the working parts areassembled; B is the beater shaft which passes longitudi nally throughthe machine and is provided preferably with sectional sleeves B uponwhich the beating straps B are secured and arranged at different anglesto secure a continual unbroken succession of blows upon the carpet, asthe shaft and sleeves revolve.

The sleeves B are loose upon the shaft Patented Sept. 2, 1919.

and spaced adjustable flange rings B, B

which are mounted upon the sleeves are connected by means of spaced rodsB, B underneath which the ends of the beating straps'are inserted, sothat by rotating the flange rings upon the sleeves the straps can bewound up upon the sleeves to increase or lessen at will the length ofthe outer and striking portions as shown in Fig. 2 at b.

The flanges are secured in any position upon sleeves B, preferably bymeans of set screws B Clutches B", B connect the several sleeve sectionswith the shaft B, so that either section can be disconnected from theshaft to stop the action of the beaters at any time. Levers B operatethese clutches. Each clutch member B engages with a complementary c, 0,formed in a depressed partition 0',

leading to the vacuum creating apparatus.

These perforations communicate directly with the ing C.

The exhaust passage C communicateswith an inclined exhaust pipe 0 whichleads to a powerful suction device or exhaust fan C through which thedust is removed from the inlet openings.

A hand hole C and cover C therefor facilitate the removal of sand oraccumulations of any kind which remain in the tube C I The aperturedgrating C is depressed at its longitudinal edges at C, C, and iscorrespondingly raised on the upper surface and is provided with alongitudinal slot C for the entrance of clean air upon each side of therows of inlet openings 0, c.

exhaust passage (3 in the grac Passages or chambers C, C for theintroductlon of clean air inclose the longitudinal slots C in the raisedportion of the apertured platform and provide a constant supply of freshair from beneath the rug, which passes upward through the longitudinalslots and rug, and is drawn downthrough the inlet perforations 0, 0,thus preventing the dusty air' from the casing from passing through therug.

The chamberspa ss through one end wall of thecasing as shown in Fig. 4.

Discharge openings C C are also pro vided giving plentiful opportunityfor the escape of the heavier dust or sand as it falls from the rugs,which travel face downwag 'd over the apertured platform- C. Theseopenings are preferably arranged intermediate of the inlet openings 0,and one or both edges of the platform, exterior to the passages 0.

Such material as passes through these openings Cf falls directly intothe cavity of the casing from whence it can be removed at pleasure.

In use the rugs are fed into the machine through a lateral opening I) inthe front .wall thereof, and thence over a horizontal screen D which isvertically adjustable by means of cams D 1) upon a rotatablelongitudinal shaft D operated by the lever D The rug is drawn over thepolished metal edge D The rugs are propelled by the combined feeding andbeating roll E mounted upon a rotatable shaft E" which propels and beatsthe rugs to remove the coarser dust and dirt therefrom before they passover the apertured platform C and underneath the beating straps B B Thisroll comprises an elastic brush formed preferably of non metallic fibersor bristles which propel the rug without wearing or tearing its back.Any dirt or dust elevated by this roll is drawn through a lateralopening E and passes through a conducting pipe E to a second blower Eshown in Fig. 1.

Transverse spring guard rods or keepers F, F, are removably attached atintervals to the sides of the casing and lie over the rug in its passageto prevent it from winding up over the propelllng roll and to cause itto lie smoothly in contact with the grating C while under the action ofthe beating straps.

These guard rods are curved at the front end to avoid the shaft E at Fand at their rear ends are doubled upon themselves at F to increasetheirelasticity so that they will not become broken under the repeatedaction of the beating straps, and at their extremities they are providedwith screw threaded ferrules F F see Figs. 8 and 9, which are screwedinto the frame, and reinforced. In this manner the rods are protectedfrom breaking where the screw threads join the casing, when they arecaused to vibrate severely by the action of the beating straps.

A final sweeping roll is shown at G mounted upon a longitudinal shaft G"at the rear of the apertured platform.

This roll sweeps andslightly lifts the ru from below as it is passingover a second grating H and the fibers or bristles G of this roll arearranged in oppositely positioned rows so as to exert an intermittentsweeping and propelling force upon the rug and to remove the hair orthread from the nap of the rug, which could not be removed by the actionof the boaters and vacuum alone.

It will be observed that when the rug passes over the depressed edges CG? of the grating C it will sag from want of support at these points andhence will become more flexible to assist the action of the heaters inremoving the dust therefrom.

The same action takes place when the ru .tioned exterior to one end ofthe casing.

Here L is a band or belt wheel mounted upon the driving shaft G uponwhich the brushing roll G is mounted. L and L are spur gears mountedupon the shafts B and G respectively and driving the beater shaft B at apredetermined rate of speed greater than that of the elastic propellingroll.

Upon the beater shaft B is shown a disk J engaged by a friction roll Jwhich is mounted upon a transverse shaft J and a worm J upon this shaftengages with a worm.wheel J upon the shaft E of the propelling roll E.In this manner the rate of s eed of the propelling roll is much reucedbelow that of the driving shaft and beaters. p i

The friction roll J can be made to travel diametrically across the diskJ to vary the speed of the worm shaft by means of the nut J operativelyconnected to J Which travels upon a screw threaded shaft J parallel tothe worm shaft. A hand wheel 5' operates the screw threaded shaft andnut. Means are also shown in Figs. 3, 10 and 11 for throwing thefriction roll J so that the propelling roll will cease operating.

This comprises a hinged member or rock arm K upon which one end of theworm shaft is mounted and a rotatable wedge or cam sleeve K having aninclined edge K which engages an inclined face upon a block K secured tothe end of-the casing. A bell crank lever K and link K rotate this camsleeve. A spring K above the cam sleeve is then raised and in turnengages one end of the hinged member K and depresses the other 'endcarrying the. friction roll and worm, so that the friction roll willmake contact with its driving disk.

The action of the spring It makes the contact resilient in eflfect.

In Figs. '1, 4 and 5 is shown a transverse slot M in the end of thecasing, opposite the driving mechanism.

This slot communicates at its ends with the longitudinal slot D in thefront wall of the machine, and the longitudinal opening M in the rearwall of the machine.

This slot permits larger rugs to be beaten than could otherwise begotten into the machine, since when one-half is beaten the rug can beturned around after leaving the machine and the other half beaten,permitting one-half of the rug to extend beyond the machine.

To support the upper portion of the end of the casing opposite thegearing horizon tally extended frames M M are positioned as shown inFigs. 1, 2 and 4, which retain the upper portion of the casing at thisend in spaced relationship to the lower portion, and the opposite endwall being integral forms a rigid support at that end.
